It is essentially the same as the version from = V7, but with 15 more years of bug fixes.

No, it derives from V7, with much stuff from 4BSD back-ported to the = PDP11. See the =E2=80=9CEarly BSDs=E2=80=9D section of the Unix Tree = (https://minnie.tuhs.org//cgi-bin/utree.pl). Although V8 also has some = 4BSD roots, the V8/V9/V10 lineage is different from the 2.8-2.11 BSD = lineage. There was a lot of code sharing back then, it is not a simple = picture. > BTW did you publish your work? https://1587660.websites.xs4all.nl/cgi-bin/9995/dir?ci=3Dtip
